HENRY BRAD, OF GREENCAS'ILE, INDIANA.` 4

BRICK-MACHINE.

Specification of Letters Patent No. 15,798, dated September 30, 1856.

To all whom it may concern Be it known that I, HENRY BRAD, of Greencastle, county of Putnam, and in the State of Indiana, have invented a new and Improved Mode of Making Brick; and I do` a revolving journal for the purpose of re-` moving the brick from the molds upon the apron. v

To enable others 'to make and use my invention and machine as invented, I disclose its construct-ion and operation.

The parts of the machine are made in any of the known forms, and are combined and operate as follows, reference being had to said drawings l, and 2.

M in Fig. l, represents the power wheel, or wheel by which the machine is propelled.

H, represents a drum, Vor roller, which is made with cogs, or teeth on the surface for the purpose of grinding the clay thoroughly, separating and removing any hard or foreign substance, such as stone, wood, grass, or any other thing calculated to obstruct, or impede the machinery. j

o, c, is a sliding plate which is made concave, to fit, and slide up to the front part of the roller H andA has teeth attached like the roller.

m, m, is a key or wedge, by which to fasten the sliding plate c, c, and by moving said plate o, o, backward and forward, you open and close the mill so as to grind the clay j as fine, or coarse, as desired.

S, represents a cistern to hold water.

e, in Fig. 1, is the hopper which carries the clay into the mill.

L, is the pitman which is attached to the press by means of a nut screwed on the end of the wrist. l

In Fig. 2, a is a frame to which a roller is attached for the purpose of removing the brick from the molds F, F, upon the apron K, is a revolving journal which operates the frame and roller oz.` F, F, are the molds into which the bricks are pressed; and b, is the apron which receives the which traverses the inclined plane T, is

made fast to the bottom of the molds F, F, so as to open them when they enter in, or under the machine, and as they return out, the inclined plane T, operates on the wrist, so as to bring the bricks level with the top, or surface ofthe apron b, so that when the roller comes in contact with the brick in refmoving them they will not be broken or injured on the edge or otherwise. D, D, in Fig. `2, represents a gate by which the water passing through the sprinkler on the clay, may be regulated at pleasure. N., is a pugmill or temperer which by its quick motion thereby mixes the mortar. N', by its slow motion works in unison with the same motion of the molds, so that when the" molds go under the machine to receive the mortar, the half wing on the ournal N', throws the mortar u nto the molds, then the press g, comes down upon the mortar, and presses the bricks as hard as desired. D, is the j gate or slide which regulates the feed of the press, which may be raised or depressed, as the feed may be desired on the machine, and by the closing may be stopped entirely, for the purpose of grinding and tempering the clay or mortar.. P, is a pitman which runs the molds, backward and forward under the machine. E, is the journal which operates the pitman P.

What I claim as my invention and desire to secure by Letters Patent is:

The self adjusting frame a, for the purpose of removing the brick from the molds onto the apron Z9, l), after they are pressed, operated by means of spring t, and projections 0, 0, on the revolving journal K, when the above part-s are constructed, arranged and operated as set forth.
